作曲家尹俊河的第三张数码单曲 Ill protect you 饱含真心的歌曲给你的心带来悸动。 这首歌包含了与心爱的恋人初次见面，在成为恋人之前表达心意阶段的感觉。 如果是恋人的话，会想怎样表达我的心才能触及到她呢？你的心也会和我一样吗？ 在表白心意之前，虽然激动又紧张，但另一方面也会记住害怕的心情。 尹俊河为她作曲作词的 Ill protect you原封不动地展现了尹俊河青涩而真挚的爱情。 Composed by 윤준하 Lyrics by 윤준하 Arranged by 윤준하, 서재하 Vocal by 노지완 Guitar by 김민규 Chorus by 서재하 Recorded by 윤준하 Mixed by 윤준하, 서재하 Mastered by 윤준하, 서재하
